GUI Theme change not initially visible in SyncTrayzor Browser

[Hard-Wired]

SyncTrayzor 1.1.21, Syncthing v0.14.48 (auto-upgraded) on Windows 10 (Home/Pro) 1803 with 2018-07 Cumulative Update.

When setting Syncthing's GUI Theme (Black, Dark, Default), the change does not initially appear in SyncTrayzor's browser until after using SyncTrayzor's menu Syncthing / Refresh browser function at least 2-3 times.

I think it' something to do with caching, but I can't figure out what: whether it's Syncthing returning 304 when it shouldn't, or the client not sending no-cache when it should. That seems to be involved with the refreshes not working anyway. Something else seems to be going on when you save the config though - this should trigger a reload, but that request to syncthingController.js gets aborted.

It isn't critical, since I would think most people only set this once, but it is annoying. I thought something had broken during a new installation, but realized it was happening on each of my systems.

Just delete the "cef" folder under data in the synctrayzor directoy. after that it worked again for me.

Right, think I've got something which more or less works. Some of the other things to try will require upgrading CefSharp, and that's going to be a fairly major undertaking.
